There is already an acronym for it "TMI", too much information. Megapixel resolution is two things, enough for good visual quality and the size of print that can be made. So who wants a camera that can print billboard size pictures? People who make billboards. ASQGASA

I'll take that as a legitimate answer. But here's a follow-up question. At what point does the human eye see differences from the increase from higher magepixel images?

I'm referencing the article that was done at this link: http://pogue.blogs.nytimes.com/2006/11/21/21pogues-posts-2/
(not sure if this has been discussed before).

Do you not realize that Pogue exercise was a deliberate piece of visual propaganda intended to deceive people? If you don't I'll explain it to you, beginning with the selection of a subject matter intended to engage viewers emotionally and one that would look attractive at almost any resolution because there was little image information involved that would look very different at any resolution.

I did not realize that a picture of a small child didn't have enough digital information to be a good test subject(how is this possible?). I can understand the 'emotional response' to the photo, but all photo's would give some type of emotional response(or we wouldn't bother to take pictures).

Scott (very curious now) B

Did you actually see the picture of the baby? It was flatly lit and other than the eyelashes, the soft, smooth face features and the fuzzy blanket surrounding the child would hardly provide anything to focus on much less distinguish if there was or was not any detail in the image that would indicate if it were a high or low resolution image.

In my articles and reports in Shutterbug if I want to illustrate differences in resolution that capture different amounts of subject detail I choose a subject like the valley on the road north of Durango, Colorado where the hills have tens of thousands of aspen trees with their white trunks and branches contrasted against the dark hillsides, and especially obvious when lit by sunlight at an angle on a clear day. With such a subject any difference in camera resolution would show up very dramatically and obviously.
